Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of electronic products, and specifically relates to an electronic device. Background Art
[0002] With the rapid development of electronic devices, consumers have put forward higher requirements for the communication performance of electronic devices. For electronic devices in recent years, the structural design of external antennas has been cancelled and turned to the structural design of internal antennas. For example, the antenna FPC is attached to the inside of the body or the metal part inside the middle frame of the electronic device is used to form the antenna.
[0003] Among them, in the solution of fitting the antenna inside the fuselage, the layout bottleneck of the antenna FPC is mainly concentrated in the external openings or connectors such as the USB charging jack, speaker hole, and MIC hole. These positions need to avoid the openings when laying out the antenna FPC. When the antenna FPC bypasses the opening, the layout space around the opening is narrow. The antenna FPC is made of soft material. When bypassing the opening, the antenna FPC is easily dislocated to the external opening due to movement, causing the antenna FPC to be easily damaged, affecting the radiation performance of the antenna. If the problem is avoided by increasing the avoidance space or adding a limit structure, the layout space of the antenna FPC will be further compressed, affecting the radiation performance of the antenna. Summary of the invention
[0004] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem that the antenna FPC is easily damaged due to the narrow antenna layout space around the appearance opening.
[0005] In order to solve the above technical problems, this application is implemented as follows:
[0006] In a first aspect, an embodiment of the present application provides an electronic device, including:
[0007] A frame body, wherein at least one through hole is provided on the frame body;
[0008] The antenna unit comprises: a plurality of antenna flexible circuit board FPC parts and at least one metal plate body;
[0009] Wherein, the metal plate is arranged on the peripheral side of the through hole, and the antenna FPC part is attached to the surface of the frame;
[0010] Two antenna FPC parts arranged on both sides of the through hole are connected through the metal plate body.
[0011] In the embodiment of the present application, a metal plate is arranged around the through hole to replace the original antenna FPC, so that the metal plate is used as the antenna conducting medium of the antenna unit at the through hole. In this way, the overcurrent carrying capacity and radiation performance of the metal plate can be increased by adjusting the thickness of the metal plate, thereby reducing the size requirements of the metal plate, achieving the effect of reducing the space requirements for arranging the antenna at the connection port, and because the material of the metal plate is hard, the metal plate is not easy to shift into the through hole, which can avoid damage to the antenna unit and ensure the radiation performance of the antenna unit.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.
[0022] The control method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.
[0023] Please refer to Figures 1 to 6 , an embodiment of the present invention provides an electronic device, including:
[0024] A frame 1, wherein at least one through hole 11 is provided on the frame 1;
[0025] The antenna unit 2 includes: a plurality of antenna flexible circuit board FPC parts 21 and at least one metal plate body 22;
[0026] The metal plate 22 is arranged on the peripheral side of the through hole 11, and the antenna FPC part 21 is attached to the surface of the frame 1;
[0027] The two antenna FPC parts 21 arranged on both sides of the through hole 11 are connected through the metal plate body 22 .
[0028] It should be noted that the through hole 11 can be an appearance hole, or a connection port for the electronic device to connect, communicate or transmit signals with the external environment or other devices. For example, the connection port includes but is not limited to: a USB charging jack, a speaker hole, a MIC hole, etc.
[0029] In specific implementation, different from the structure of the antenna FPC in which the metal wire is wrapped inside the protective substrate, the metal plate body 22 in the embodiment of the present application is a plate-shaped metal part. For example, the metal plate body 22 is a steel sheet, an aluminum sheet, or a copper sheet.
[0030] As an implementation method, the metal plate 22 can be attached to the surface of the frame 1 .
[0031] As another implementation manner, the metal plate body 22 is embedded in the frame body 1 , and the metal plate body 22 is covered by the frame body 1 , and the frame body 1 is used to form a protective layer for the metal plate body 22 .
[0032] As another implementation manner, the metal plate body 22 is disposed in a recessed area or groove of the frame body 1 .
[0033] In the above embodiment, the antenna FPC is disconnected at the through hole 11 to form an antenna FPC part, that is, an antenna FPC segment, and then the two adjacent antenna FPC parts located on both sides of the through hole 11 are connected via the metal plate 22, and the metal plate 22 is used as the antenna conductive medium of the antenna unit at the through hole 11. In this way, the overcurrent carrying capacity and radiation performance of the metal plate 22 can be increased by adjusting the thickness of the metal plate 22, thereby reducing the size requirements of the metal plate 22, so as to reduce the space requirements for the layout of the antenna at the through hole 11, and because the material of the metal plate 22 is hard, the metal plate 22 is not easy to be dislocated to the through hole 11, which can prevent the antenna unit 2 from being damaged, improve the reliability of the antenna unit 2, and ensure the radiation performance of the antenna unit 2.
[0034] In some embodiments, the metal plate body 22 includes a main body portion 221 and connecting portions 222 located at both ends of the main body portion 221;
[0035] The main body portion 221 is connected to the antenna FPC portion 21 located on both sides of the through hole 11 through two connecting portions 222 .
[0036] As an example, Figure 2 In the embodiment, the metal plate body 22 is a bent piece of an “X”-shaped structure. For example, the metal plate body 22 can be cast into a steel sheet insert of an “X”-shaped structure, so that the main part 221 and the connecting part 222 are located in different planes, the middle part of the “X”-shaped structure is the main part 221, and the two ends of the “X”-shaped structure are the connecting parts 222, so that the main part 221 is embedded in the frame 1, and the connecting parts 222 are exposed on the surface of the frame 1.
[0037] As another example, the main body and the connecting portion 222 of the metal plate body 22 are both flat plate structures, and the planes where the two are located are located in the same extension plane. This structure is suitable for attaching the metal plate body 22 to the surface of the frame body 1.
[0038] In some embodiments, the main body 221 is embedded in the frame 1, and the frame 1 covers the main body 221;
[0039] The connecting portion 222 extends from the inside of the frame 1 to the surface of the frame 1 .
[0040] For example, Figure 1 and Figure 2 In the figure, the main part 221 in the metal plate body 22 is embedded in the frame 1 in advance, and the connecting part 222 is extended to the surface of the frame 1 in a position area away from the through hole 11, so that the connecting part 222 is exposed on the side of the frame 1 where the antenna FPC is arranged. In this way, the antenna FPC part can be electrically connected through the connecting part 222.
[0041] In some embodiments, the frame 1 and the metal plate 22 are integrally formed.
[0042] Exemplarily, the frame 1 is a plastic structure, and the frame 1 and the metal plate 22 are integrally formed, so that the metal plate 22 is wrapped in the frame 1 of the plastic structure, so that the metal plate 22 is protected by the plastic structure.
[0043] In this way, the metal plate body 22 is used to replace the FPC layout at the through hole 11. Since the metal plate body 22 itself is entirely a flow medium, after the metal plate body 22 is embedded in the frame 1, the plastic wrapping the metal plate body 22 can protect the metal plate body 22. Unlike the traditional antenna FPC structure design, there is no need to leave space for protecting the substrate and the assembly gap, which can avoid the problem of reducing the size of the FPC at the through hole 11 due to the limited layout space.
[0044] In some other embodiments, a recessed area is disposed around the through hole 11 , the main body 221 is disposed in the recessed area, and the connecting portion 222 extends from the recessed area to the surface of the frame 1 .
[0045] like Figure 1 In the case of Figure 1 The area shown by the dotted line.
[0046] In this embodiment, a recessed area is provided on the peripheral side of the through hole 11, and the main body 221 is provided in the recessed area. Compared with embedding the main body 221 in the metal plate 22 in the frame 1 in advance, this solution facilitates the installation and removal of the metal plate 22, and the metal plate 22 provided in the recessed area is not prone to displacement, which can improve the performance stability of the antenna unit. For example, double-sided tape is applied in advance in the recessed area, and the main body 221 is fixed in the recessed area by the double-sided tape.
[0047] In some embodiments, the main body portion 221 is covered with a first protective layer on a side facing away from the recessed area, and the first protective layer and the recessed area form a sealed space for accommodating the main body portion 221 .
[0048] Exemplarily, the first protective layer is a UV adhesive layer. UV adhesive is a light-curing adhesive whose main component is photosensitive resin. Its curing process depends on the irradiation of ultraviolet light. When the UV adhesive is exposed to ultraviolet light, the photosensitive components in the adhesive will undergo a chemical reaction, quickly cure and form a hard adhesive layer.
[0049] In this embodiment, by disposing the main body 221 in the sealed space formed by the first protective layer and the recessed area, the main body 221 can be protected and the main body 221 can be prevented from escaping from the recessed area and becoming dislocated.
[0050] In some other embodiments, the main body 221 is attached to the surface of the frame 1 ; the two connecting portions 222 and the main body 221 are extended along the curved surface area formed by the circumference of the through hole 11 .
[0051] like Figure 1 As shown, a curved area is formed on the circumference of the through hole 11, and the two connecting parts 222 and the main body 221 are extended along the curved area formed on the circumference of the through hole 11. In this way, the layout size of the metal plate body 22 can be increased and the radiation performance of the antenna unit can be enhanced.
[0052] In some embodiments, the antenna FPC portion 21 exposes a metal trace at one end close to the through hole 11 and is electrically connected to the metal plate body 22 through the metal trace.
[0053] In a specific implementation, two antenna FPC parts 21 are arranged on both sides of each through hole 11, and the antenna FPC part 21 is broken at one end close to the through hole 11, exposing the metal trace at the break, and the metal trace is welded to the metal plate body 22 to realize the use of the metal plate body 22 as the antenna conductive medium of the antenna unit at the through hole 11.
[0054] In some embodiments, the connection position between the metal trace and the metal plate 22 is covered with a second protective layer 3 .
[0055] For example, Figure 3 The dotted line in FIG. 1 shows the position of the main body 221 inside the frame 1. Figure 4 It is shown that the second protection layer 3 covers the connection position between the metal trace and the metal plate body 22 .
[0056] In a specific implementation, after the metal wiring is welded to the metal plate body 22 , a glue dispensing process is performed at the connection position between the metal wiring and the metal plate body 22 to form a sealing protective layer to prevent the connection position from being corroded and affecting the radiation performance of the antenna unit 2 .
[0057] In some embodiments, the frame 1 includes a frame, and a hollow space 12 formed by the frame;
[0058] At least two antenna units 2 are spaced apart on the frame.
[0059] For example, Figure 5 As shown, the frame 1 includes four frames, which enclose a hollow space 12. An antenna unit 2 is respectively arranged at position B and position C of the frame. Taking the partial enlarged view at position B as an example, after hiding the frame 1, the structure of the antenna unit 2 is as follows: Figure 6 As shown, two ends of the metal plate body 22 are respectively connected to an antenna FPC part 21 , and the metal plate body 22 is used as an antenna conducting medium of the two antenna FPC parts 21 .
[0060] In some embodiments, the frame 1 includes: a frame and a middle plate, wherein the frame is bent and connected to the periphery of the middle plate; at least one through hole 11 and at least one antenna unit 2 are provided on the middle plate.
[0061] In some embodiments, the electronic device further comprises:
[0062] Mainboard bracket (not shown), antenna FPC21 is sandwiched between the mainboard bracket and the frame 1;
[0063] Screen, the screen is fixedly connected to the mainboard bracket;
[0064] The metal plate 22 is disposed on a side of the through hole 11 close to the screen.
[0065] Exemplarily, the mainboard bracket is connected to the periphery of the frame 1 , and the mainboard bracket and the frame 1 are arranged to form a receiving space, and the receiving space is used to store batteries and various components.
[0066] For example, Figure 5 and Figure 6 As shown, the side wall where the through hole 11 is located is perpendicular to the plane where the screen (not shown) is located, and the metal plate body 22 is arranged on the side of the through hole 11 close to the screen.
